You're playing with yourself when step-mom suddenly comes into the room, asking what you want for dinner. She's embarrassed at first, but then she sees how small your dick is and has to laugh. She feels so bad that you have to go through life with such a little dick, but she can't stop making fun of it. After all of that, she leaves to go make dinner. She figures you want burgers instead of hot because you might feel threatened by the latter.
